Threat Intelligence
Cyber threat intelligence (CTI) is a subfield of cybersecurity that focuses on the structured collection, analysis, and dissemination of data regarding potential or existing cyber threats. It provides organizations with the insights necessary to anticipate, prevent, and respond to cyberattacks by understanding the behavior of threat actors, their tactics, and the vulnerabilities they exploit. Cyber threat intelligence sources include open source intelligence, social media intelligence, human Intelligence, technical intelligence, device log files, forensically acquired data or intelligence from the internet traffic and data derived for the deep and dark web. In recent years, threat intelligence has become a crucial part of companies' cyber security strategy since it allows companies to be more proactive in their approach and determine which threats represent the greatest risks to a business. This puts companies on a more proactive front, actively trying to find their vulnerabi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cybersecurity
Computer security (also cybersecurity, digital security, or information technology (IT) security) is a subdiscipline within the field of information security. It consists of the protection of computer software, systems and networks from threats that can lead to unauthorized information disclosure, theft or damage to hardware, software, or data, as well as from the disruption or misdirection of the services they provide. The significance of the field stems from the expanded reliance on computer systems, the Internet, and wireless network standards. Its importance is further amplified by the growth of smart devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT). Cybersecurity has emerged as one of the most significant new challenges facing the contemporary world, due to both the complexity of information systems and the societies they support. Security is particularly crucial for systems that govern large-scale sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zero-day (computing)
A zero-day (also known as a 0-day) is a vulnerability or security hole in a computer system unknown to its developers or anyone capable of mitigating it. Until the vulnerability is remedied, threat actors can exploit it in a zero-day exploit, or zero-day attack. The term "zero-day" originally referred to the number of days since a new piece of software was released to the public, so "zero-day software" was obtained by hacking into a developer's computer before release. Eventually the term was applied to the vulnerabilities that allowed this hacking, and to the number of days that the vendor has had to fix them. Vendors who discover the vulnerability may create patches or advise workarounds to mitigate it – though users need to deploy that mitigation to eliminate the vulnerability in their systems. Zero-day attacks are severe threats. Definition Despite developers' goal of delivering a product that works entirely as intended, virtually all software and hardware contain bugs. ...

Ransomware
Ransomware is a type of malware that Encryption, encrypts the victim's personal data until a ransom is paid. Difficult-to-trace Digital currency, digital currencies such as paysafecard or Bitcoin and other cryptocurrency, cryptocurrencies are commonly used for the ransoms, making tracing and prosecuting the perpetrators difficult. Sometimes the original files can be retrieved without paying the ransom due to implementation mistakes, leaked cryptographic keys or a complete lack of encryption in the ransomware. Ransomware attacks are typically carried out using a Trojan horse (computing), Trojan disguised as a legitimate file that the user is tricked into downloading or opening when it arrives as an email attachment. However, one high-profile example, the WannaCry worm, traveled automatically between computers without user interaction. Starting as early as 1989 with the first documented ransomware known as the AIDS (Trojan horse), AIDS trojan, the use of ransomware scams grew inter ...

Malware Analysis
Malware analysis is the study or process of determining the functionality, origin and potential impact of a given malware sample such as a virus, worm, trojan horse, rootkit, or backdoor. Malware or malicious software is any computer software intended to harm the host operating system or to steal sensitive data from users, organizations or companies. Malware may include software that gathers user information without permission. Use cases There are three typical use cases that drive the need for malware analysis: * Computer security incident management: If an organization discovers or suspects that some malware may have gotten into its systems, a response team may wish to perform malware analysis on any potential samples that are discovered during the investigation process to determine if they are malware and, if so, what impact that malware might have on the systems within the target organizations' environment. * Malware research: Academic or industry malware researchers may per ...

Denial-of-service Attack
In computing, a denial-of-service attack (DoS attack) is a cyberattack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to a network. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled. The range of attacks varies widely, spanning from inundating a server with millions of requests to slow its performance, overwhelming a server with a substantial amount of invalid data, to submitting requests with an illegitimate IP address. In a distributed denial-of-service attack (DDoS attack), the incoming traffic flooding the victim originates from many different sources. More sophisticated strategies are required to mitigate this type of attack; simply attempting to block a single source is insuffic ...

Cyber Intelligence Sharing And Protection Act
The Cyber Intelligence Sharing and Protection Act (CISPA (112th Congress), (113th Congress), (114th Congress)) was a proposed law in the United States which would allow for the sharing of Internet traffic information between the U.S. government and technology and manufacturing companies. The stated aim of the bill is to help the U.S. government investigate cyber threats and ensure the security of networks against cyberattacks. The legislation was introduced on November 30, 2011, by Representative Mike Rogers (Michigan politician), Michael Rogers (Republican Party (United States), R-List of United States Representatives from Michigan, MI) and 111 co-sponsors. It was passed in the House of Representatives on April 26, 2012, but was not passed by the U.S. Senate. President Barack Obama's advisers have argued that the bill lacks confidentiality and civil liberties safeguards, and the White House said he would veto it.

Cybersecurity Information Sharing Act
The Cybersecurity Information Sharing Act (CISA 113th Congress, 114th Congress) is a United States federal law designed to "improve cybersecurity in the United States through enhanced sharing of information about cybersecurity threats, and for other purposes". The law allows the sharing of Internet traffic information between the U.S. government and technology and manufacturing companies. The bill was introduced in the U.S. Senate on July 10, 2014, and passed in the Senate on October 27, 2015. Opponents question CISA's value, believing it will move responsibility from private businesses to the government, thereby increasing vulnerability of personal private information, as well as dispersing personal private information across seven government agencies, including the NSA and local police. The text of the bill was incorporated by amendment into a consolidated spending bill in the U.S. House on December 15, 2015, which was signed into law by President Barack Obama on Decembe ...
